The
B-29s that dropped the atomic bombs on Japan were built in Nebraska?

In February 1941 the Glenn L. Martin
Company and the U.S. government began plans for an aircraft assembly
plant at Fort Crook, Nebraska.
At its peak in November 1943, the Martin Bomber Plant employed
14, 527 persons. In two years, 1, 585 B-26 Martin Marauders rolled
off the Omaha assembly line. By the summer of 1943 the plant
began production of a new four-engine bomber-the Boeing B-29
Superfortress. More than five hundred were produced, including
the Enola Gay and Bockscar, which dropped the atomic
bombs on Hiroshima and Nagasaki.
